Thread: Whether your man smells stale or sweet to you or not depends on your genes

    Whether your man smells stale or sweet to you or not depends on your genes

    Apparently, the male sex hormone androstenone is a "potent ingredient" of male body odor. Some people find the smell repulsive, like stale urine. Others find that it smells like vanilla, sweet and pleasant.

    Well, in this study by a group of scientists from Rockefeller, they have identified the olfactory receptor and the gene for smelling androstenone. Called OR7D4, this receptor plays an important role in determine whether your man smells stale or sweet to you.
    Gene determines whether male body odor smells pleasant (9/18/2007)

    To many, urine smells like urine and vanilla smells like vanilla. But androstenone, a derivative of testosterone that is a potent ingredient in male body odor, can smell like either - depending on your genes. While many people ascribe a foul odor to androstenone, usually that of stale urine or strong sweat, others find the scent sweet and pleasant. Still others cannot smell it at all.

    New research from Rockefeller University, performed in collaboration with scientists at Duke University in North Carolina, reveals for the first time that this extreme variability in people's perception of androstenone is due in large part to genetic variations in a single odorant receptor called OR7D4. The research is reported September 16 as an advance online publication of the journal Nature.

    Androstenone, found in higher concentrations in the urine and sweat of men than of women, is used by some mammals to convey social and sexual information, and the ability to perceive androstenone's scent may have far-reaching behavioral implications for humans.

    Roses are red. Tacos are enjoyable. Don't blame immigrants, because you're unemployable.

    Heard this story on NPR the other day, very interesting, the power of influence from one gene variable, where sense of smell is influenced by hundreds(?) of genes.

    Listen to the story on the link below...
    Research Links Smelling Differences to Gene

    All Things Considered, September 16, 2007 ยท A new study suggests that people smell scents differently because of their genes.

    For example, a smell found in male body odor, called androstenone, has intrigued researchers for decades. Some people say it's like vanilla, others compare it to sweat or urine and some people can't smell it at all. Scientists have linked the difference to variations in the gene for the receptor that responds to the odor.

    Gee whiz...Give me a motorcycle guy that's been riding/working on a bike and I'm crazy by the smell... Just riding on the back of his bike with my face in his hair is a total turn on!...
